,Patented June Y11, 1935` c [UNITED STATES :PATENTIf OFFIC-E" The present invention relates teV mandrels used 'in the productionoffpermanentwaves in the hair. `In the mandrelsfor waving hair that are now in common use, the means provided for clamping the lock of hairto be wound is commonly located I and thefpartsin'clampingposition at oneend of the mandrel extendingjoutwardly therefrom. Consequently thesurfaceupon which the `hair is wound is more or less uneven,`instead ofbeing Wholly smooth and freefrorn obstruction as is desirable for thesmooth and veven wrapping (necessaryfor good results. n

- The object of the invention is to provide a mandrel having a smooth cylindrical surface :upon which the hair is to `be Wound, andjmeans entirely Withinthe surface of themandrel for clamping a lock o hair to beswo'undupon the mandrel. n H Y Anotlfier` object isi to provide in such a mandrel "easily operated means for quicklyl andeffectively clamping a lockof hair." n L Infthe accompanying dravvingz` c" Figure 1 is aperspective vieWo-fthe inga lock of hair would thereon. f c

` ofthishead isacircular channel I`2,1the inner circumference of which 'is equal tothe fcircumfer# ence" ofthe `core"I`I.`

At a point slightly spaced from the inner face of the head II, the core I0 is cutaway tonform a reduced portion I3 longitudinally eccentric to i the core I0 and having an outer transversely dis-` posed cam surface I 4 Which approaches the plane of the surface ccf the core I0.` It is to be noted device hav- Figure 81 is a perspective viewof the core mem? i that this cam surface I 4 does not at any .point extend beyond the surface of the core I0, and that it is longitudinally flat`` Y s c c if Y, Surrounding the core IU and rotatably mount# c ed thereon is a tubular `sheath upon which the *15 hair isintended to be Wound- This sheath Amay be made in sections I5 and I6.

. The section I5`isV positioned adjacent the head II and itsend is engagedin the slot I2.` Theendof `the member `I5 `Which abuts thehead of the 110 core has `diametrically opposite slots Il', the edges of which are designated i8.' Thesl'ots I'I extend longitudinally a distance `at least as'great as the cutaway portion of thecore.

The `member It abuts the `:flamber [s andexi tends'longitudinally a short' distance `beyond the endiof the core memberI, Where it carries a `sc'revv` I9,A havingthreadsthat are preferably sharply `pitched for 'quiclractiornv this screvv Aengaging a threaded socketin the adjacent end 20 ofthelcore.` .j l" j .n

`In order to prevent the sheath I6 from turning due to the reaction of h'airw'ound thereon,` tolwit,

its tendency to unwind, and thus allowingrthe hairfto become loose aboutthe device, aespecial 25 ,typeof spring-pressed plunger is'employed. `The plunger designated 20 and its backing spring', is received inasquarefsocket'in the core member 10. The plunger `consists of a `square base 2I`, which keeps it from turning, and has a stud 30 3 22 projecting therefrom. The stud 22 is of no greater height than the thickness of the Wall of the sheath I6; j j c Thestud 22`has one flat surface or faceandthe 1 rest of its surface is roundedoi. l 35 Properly positionedto4 receive the stud221of the plunger is a seriesof holes 23 in the `sheath I6.` Itwill be understood from consideration of Figure 9,` that dueto the `ilat faceand rounded surface of the stud'thecore may bemoved relativelyJ to 40' the sheath I6|in any `direction except thatv in Whichthe flatfaceis positioned.` In use this `face is turned inthe direction opposite to that `in which the" hair is Wound; thus holding `the sheath fagainst'rotation in a direction to permit 451 `the\tender1 `:yof the hair to `uncoilto lcause `the sheathV to` -rotate upon" the core; Due to` the `rounded surfacef the sheath may, however,A be

pulled?.` longitudinally from `the Y core, or` turnedin the direction to tighten the hair thereon.

- AWhen the device is to `loe used, the screw I9 is loosened and the sheath sections `are pulled away and the sheath member I5 turned so 'that the lock of hair passes through the slots Il, when the member is returned to its position with its end engaged in the channel I2. The core Ii) and the member I5 are then relatively rotated in the proper direction, with respect to the cam face I4, to cause the cam face to approach one of the edges I8 of one of the slots, thus securely clamping the lock of hair. The sheath member I5 now may be placed adjacent the member I5 with the stud 22 ofthe plunger engaged in :one ofithaholes 23, and `secured lby tightening the screw I9, thus clamping the sheath I5 against the head I I. vIt will be noted that instead of bunching the hair the clamp acts to flatten the lock. After this the operator winds the hair upon the surfaces of the sheath sections I5 and Ifand 'securesfit by any suitable means, not hereshown.

The advantages of this device are that it pre-` sents a smooth hair supporting surfacepun-brolzen by anything which might .cause the forming of kinks in the hairbeing treated. Further, it provides simple and easily operated .means for securely clamping `the hair without ycutting or breakingit, and without ,causing any shaip `bend therein to spoilthe .eiect or the waveland.also means to prevent the parts from slipping due to Vthe tendencyof the wound hair to unwind. The device is easily manufactured and of few parts'hence may be made very inexpensively.

.From the foregoing, it is thought that the construction, operation and many .advantages of the herein .described 'invention will be apparent to those skilled inthe art Without further description, ,and it .will be understood that various changes inthe size, shape, proportion and minor details oi construction maybe resorted to without departingfrom the spirit or sacrificing any ofthe advantages of the invention'.
